Firstly, ignore the free tab offer, that will only lead you to decide for the wrong reason.
Cashback is nice, but only if you remember to send the form back.
On your points:
1) I prefer a viewfinder for a lot of situations, especially in bright daylight outside when you'll struggle with screens.
2) rotating screen, very handy for taking photos at tricky angles. I love mine.
3) Shutter speed of 1/8000, you're very unlikely to ever go that high. I barely get up to 1/4000 when shooting in bright summer sun. Not a deal killer.
They are two differing styles of camera, an SLR-type or a compact type.
So you really need to go check them out in a shop, see how they feel in your hand as you will spend a lot of time holding them.
Do you want something small to fit in a pocket or are you happy carrying something bigger?
Never buy a camera just from reading the specs.
Go to Jessops (the easiest chain to find) and try them out along with a proper DSLR and compacts like a Sony NEX5, Nikon J1 and others, then decide.
